:Beit known that I, CLAUDE D. ENocHs, a citizen of the United States, residing at East Shore Park, in the county of Vlaslr` ington and State= of :Minnesota, have in-` vented` certain new randV useful Improve ments in.Animal-Oilers, of.` which the f0l lowing isa specification.

rFhis invention relatesparticularly to that.

t ige/lof 1 animal `o-ner;` ada ated to denosit a certain amount of oil on an animal that rubs against a'portionof' theoiler, through this act operating the oiling mechanism.

@ne object of my invention is to provide in an animal oiler` an oil chamber, a reservoir adapted to maintain the level of the oil in the chamber substantially uniform, and means for sweeping out a definite amount of oil through a plunger action, but without employing any valves.

Another object of my invention is to provide'in an animal oiler having a constant level oil chamber, a plunger sweeping in the oil and connecting linksrfrom the vplunger to the rubbing post of such fashion that the movement of the rubbing post will operate the plunger. n

Another object of my invention is to provide in an animal oiler having a constant level chamber, a force feed means that will operate without any valves and without any close-liitting parts that might be gummed or stuck in rough out-door service.

With these and incidental objects in view the invention consists of certain novel features of construction and combination of parts, the essential elements of which are oiler, with a portion of set forth in appended claims and a preferred form of embodiment of which is lhereinafter described with reference to the drawing which accompanies and forms a part oft-his specification.

The drawing discloses in Figure l a side elevation partly in section of my improved the central part of the supporting standard broken away, and in Fig. 2 a cross section taken on the line 2-2 of Fig. 1.

A `tank 1, Fig.v 1, having an opening at Q, but otherwise air-tight, is supported at 3 by a frame 4, so with liquid in the tank it will feed into the chambers 5 up to the, level shown in Fig. 1, when the liquid will seal the opening tube, thus preventing any more liquid from fiowing out of the tank l until AivIMAL-QILER..`

Specification of Letterslratent. ,Patented @(313, 28,1919, Application filed March 11, 1916. Sera1N0;83,527."

from thechamber 5, the three chambers be-v 8 at9-yand cennectedto the animal actuatedpost byfthe linkl 101 will be* moved Vup from the position shown full* in Fig. 1` to the position shown dotted in Fig. l, sweeping with it a certain amount ofliquid, which will be` forced out of the nozzle 11 to the animal standing adjacent to the, point 12 and any amount that is not expelled forcibly during this act will trickle slowly down on to the lip 13, and from there along the surface 14 of the animal actuated post 6, so that this liquid will eventually be deposited on the animal rubbing` thereon.

\ The plunger 7 does not necessarily have to bea close lit to the chamber 15 in which it swings, as it is evident that even though a ccnsider'able amount of liquid leaks by the plunger, a certain amount will always be swept up ahead of the plunger and forced out of the nozzle 11, and ,as the level of the liquid is always maintained constant and as the motion of the` plunger will always be rapid even though the motion of the animal actuated post is comparatively slow, it is evident that substantially the same amount of liquid will be delivered through the pipe 11 each time it is moved in thedirection of the arrow and that no further amount will be delivered if the post is held against the stop 16 for a considerable length of time.

While I have described my inventionand illustrated it in one particular design, 1 do not wish it understood that I limit myself to this construction, as it is evident that the application of my invention may be varied in many ways within the scope of the following claims.V Y

. Claims:

1. In an animal oiler the combination of a liquid chamber, the wall of which joins at one portion with the wall of aninverted cup so that liquid stands at the same level in vsaid inverted cup and said chamber, a plunger sweep hinged to a support carried by said liquid chamber and adapted to swing upwardly into said inverted cup, said inverted cup having an aperture above the liquid level thereof through which oil may be swept by said plunger sweep, and animal actuated means Jfor actuating said plunger sweep.

2. In an animal oiler'the Combination of a liquid chamber, an inverted cup, one portion of the wall of said liquid chamber forming a portion of the wall of said inverted cup, the remainder of the wall of said inverted cup being so fashioned that liquid in Said cup and said chamber will be at the same level, a support carried by said liquid chamber, an L shaped member having' a plunger Sweep on its free end hinged t0 said support, said kplunger sweep being adapted to swing into said inverted cup, and said inverted eup having an aperture above the liquid level thereofthrough which Voil may be swept, and animal actuatedv means for swinging said L shaped arm.

3. In an animal oiler the combination of a liquid chamber, an inverted eu'p joined thereto and having one portion of its wall positioned just above the liquid level of said liquid chamber, whereby oil may stand at one'level in said chamber and said inverted cup, a support carried by said liquid chamber7 a plunger sweep hinged to said support and adapted to swing upwardly in to said inverted cup, the inner and outer walls oi' said inverted cup being curved on substan tially the same radii as that portion of the plunger sweep adjacent thereto, so that, durinthe travel of said plunger sweep, the distances between the inner and outerwalls-of Vsaid inverted eup and the adjacent edges of said plunger sweep remain substantially Constant, and animal actuated'means for swinging said plunger sweep.
